Definitions

  • the present invention relates to nonwoven material for use as an absorbent wiping material and a method for producing nonwoven material.
  • Absorbent nonwoven material is often used as a wiping material. It can be used to wipe up spillages and leakages in industrial, catering, office, hospital and domestic environments. There is often a desire to provide such materials with an image or decoration, for example a logotype.
  • One common method of making images or decorations on nonwoven materials is to emboss images, the fibres are compressed by an embossing stamp.
  • thermal embossing means that a number of fibres are caused to melt and are damaged, which reduces the softness of the surface, and this in turn impairs the strength characteristics of the material.
  • the embossed image will also be situated beneath the base level of the nonwoven material, which leads to the image being less readily visible.
  • Images or decorations in nonwoven material can also be produced by hydroentangling. This can be done, for example, by means of hydroentangling against an image transfer surface.
  • a substrate web of fibres is laid on the image transfer surface, the substrate web is hydroentangled, that is to say it is sprayed with jets of liquid.
  • the image transfer surface can be in the form of a wire gauze or a plate that exhibits depressions and/or projections.
  • the nonwoven material receives its image or decoration against the wire gauze or the plate by being formed respectively against depressions and projections with the help of jets of liquid, and the nonwoven material receives an image or a decoration on both sides.
  • a method of this kind is described in WO 02/04729 .
  • a nonwoven material produced in accordance with this method exhibits certain shortcomings with regard to liquid distribution and absorption, wiping on uneven surfaces and wiping of materials of different characters. Moreover, the resulting image is not so clear.
  • WO 03/083197 Another method for hydroentangling is described in WO 03/083197 , where a nonwoven material with protuberances is produced.
  • a plastic gauze is used as the carrier device for a web of fibres when it is hydroentangled.
  • a clear image is not obtained in the material, and it exhibits shortcomings with regard to liquid distribution and absorption, wiping of materials with different characters and wiping on uneven surfaces.
  • the intention of the invention is to solve the above problems and to make available improved wiping materials made of nonwoven material.
  • the object of the present invention is to make available a strong nonwoven material that possesses good absorption characteristics and wiping characteristics, and in addition has clear images in the form of decorative surface structures or decorations.
  • nonwoven material intended for use as an absorbent wiping material produced by the hydroentangling of a substrate web comprising at least one layer of fibres selected from amongst synthetic fibres, regenerated fibres and natural fibres, wherein the nonwoven material has a base level with protuberances on one side.
  • the protuberances form at least a first and a second surface structure respectively in the form of first and second protuberances from the base level, wherein the first protuberances have a height h 1 from the base level and the second protuberances have a height h 2 from the base level, where h 2 is higher than h 1 , and each of the second protuberances occupies an area of the surface of the base level at least 4 times greater than each of the first protuberances.
  • a method for producing a nonwoven material by hydroentangling a substrate web of fibres selected from amongst synthetic fibres, regenerated fibres and natural fibres.
  • the method involves the steps of transferring the substrate web, which comprises natural fibres having a length of less than 10 mm, to a surface-shaped carrier device containing holes which form at least a first and a second pattern in the form of first and second holes respectively, wherein the second holes are at least 4 times larger than the first holes, and of hydroentangling the substrate web on the carrier device by means of jets of liquid under high pressure, so that the fibres of the substrate web penetrate down into the holes.
  • FIG. 1 An embodiment of a nonwoven material in accordance with the invention is shown in Figure 1 .
  • the present invention thus relates to a nonwoven material 1 for use as an absorbent wiping material, produced by hydroentangling of a substrate web comprising at least one layer of fibres selected from amongst synthetic fibres, regenerated fibres and natural fibres, wherein the nonwoven material 1 has a base level h 0 with protuberances 2, 3 on one side, wherein the protuberances 2, 3 constitute at least one first and one second surface structure respectively in the form of first and second protuberances 2, 3 from the base level h 0 , wherein the first protuberances 2 have a height h 1 from the base level h 0 and the second protuberances 3 have a height h 2 from the base level h 0 , where h 2 is higher than h 1 , and each of the second protuberances 3 occupies an area of the surface of the base level at least 4 times greater than each of the first protuberances
  • hydroentangling or “spunlacing” are used here to denote that fibres are tangled together by means of very fine jets of liquid under high pressure. Several rows of jets of liquid are directed at the fibre web or the substrate web, which is supported by a wire gauze or a drum. The entangled web is then dried. A nonwoven material with a well-integrated composition is obtained as a result.
  • Also proposed in accordance with the present invention is a method, which can be seen in hydroentangling stage 108 in Figure 3 , for producing a nonwoven material 111 by hydroentangling a substrate web 101 of fibres selected from amongst synthetic fibres, regenerated fibres and natural fibres, wherein it includes the following steps:
  • the proportion of natural fibres having a length of less than 10 mm used in the method is preferably at least 5% by weight.
  • substrate web denotes a pre-formed fibre web that is capable of being produced by one or other conventional means. Fibres are laid down onto a forming wire gauze. Continuous filaments are laid down, for example, by the meltblown or spunlaid technique, and staple fibres and pulp fibres can be wet-laid or dry-laid.
  • carrier device is used here to denote the device which supports the substrate web when it is hydroentangled, and this serves the purpose at the same time of imparting an image/structure to the nonwoven material.
  • the carrier device should be made of a material that is sufficiently hard for hydroentangling, that is to say it should be inflexible during the hydroentangling stage. Plate or nickel plate are suitable materials.
  • surface-shaped denotes that the carrier device exhibits a plane and uniform surface, for example in the form of a sheet material.
  • This can consist of a sheet of plate with holes of different sizes.
  • the sheet has a uniform and plane surface, which we define as "surface-shaped”. Holes are arranged on this surface-shaped carrier device.
  • the sheet of plate can be formed as a drum, although it has no separate projections or depressions, but the sheet of plate is "surface-shaped" or two-dimensional with holes.
  • the forming wire gauze 102 is caused to advance together with the continuous filaments to a wet-laying stage, where a slurry consisting of a mixture of natural fibres 105 and staple fibres 106 is wet-laid onto, and partially into, the layer 104 of continuous filaments in the substrate web, and any surplus liquid is drained off by the forming wire gauze 102.
  • the substrate web can then be bonded together in such a way that it holds together in a satisfactory fashion for further processing. Bonding can be effected by pre-hydroentangling, as illustrated by way of example in stage 107 in Figure 3 .
  • the forming wire gauze 102 conveys the substrate web 101 to the hydroentangling stage 108, where the substrate web 101
  • the hydroentangling stage for the surface structure can take place alternatively on a wire gauze loop.
  • the drum or the loop is covered with a suitable surface-shaped material containing holes in accordance with the invention and constitutes a carrier device.
  • the number of nozzles per drum is around 1 to 3, although a larger number of nozzles can also be present.
  • Bonding can take place in a pre-hydroentangling stage 107, which precedes the hydroentangling 108 on the carrier device 109 in accordance with the invention.
  • Pre-hydroentangling intended for bonding of the substrate web can take place on one or both sides of the substrate web. In the case of hydroentangling on both sides, for example, two drums positioned one after the other can be used, where one side of the substrate web is pre-hydroentangled on the first drum, and the second side is pre-hydroentangled on the second drum.
  • pre-bonding of the substrate web for example in the form of pre-hydroentangling, may be necessary.
  • the substrate web must hold together sufficiently well to enable it to be moved to the hydroentangling stage on the carrier device when the substrate web is to be given its surface structure.
  • the filaments 103 are produced from extruded molten plastic that is laid down directly onto the forming wire gauze 102.
  • the filaments 103 can be cooled with air 112 to enable them to solidify before they come into contact in order to form a non-bonded layer 104.
  • the natural fibres 105 and the staple fibres 106 are suspended in a conventional way, either together or individually, and are then mixed and wet-laid onto the layer 104 on the substrate web.
  • the mixture is pumped out from a flow box 113 for wet-laying. Surplus liquid is sucked out through the forming wire gauze 102.
  • the method of producing the substrate web is shown here for illustrative purposes only, and it is not restrictive.
  • the stage at which continuous filaments 103 are laid down is not necessary in this case.
  • the method in accordance with the invention relates essentially to the hydroentanglement stage of a substrate web.
  • the carrier device can be manufactured from a metal plate or a sheet of sufficient hardness to enable it to function as a support in conjunction with hydroentangling.
  • the plate or the sheet must exhibit a plane and uniform surface, and it must contain the holes that are intended to impart the surface structure. It is preferable for the carrier device to be formed as a cylinder.
  • a nonwoven material in accordance with the invention is obtained by the new method.
  • a nonwoven material of this kind has protuberances of different heights, and these protuberances occupy different areas of the surface of the base level of the nonwoven material. This results in a nonwoven material with a good liquid distribution, absorption capacity and good comfort during use, advantages that are described in greater detail below.
  • the hydroentangling of the fibres causes the quantity of fibres to vary between protuberances with a different height and surface extent in the base level and the material in the rest of the nonwoven material.
  • the expression "rest of the nonwoven material” is used to denote those parts that lie between the protuberances in the extent of the plane of the nonwoven material.
  • the variation of the fibres depends both on the pressure in the jets of liquid and on the composition of the fibres in the material. Different fibres are caused to move with greater or lesser ease by the act of spraying liquid against the substrate web on the carrier device. Short fibres are able to move more easily, for example. This results in a nonwoven material with a good capacity to absorb different materials. Hydroentangling also results in the creation of a strong nonwoven material.
  • the image transfer surface has exhibited depressions and/or projections of the kind disclosed in WO 02/04729 , for example.
  • An image transfer surface of this kind can be regarded as three-dimensional.
  • a carrier device which transfers surface structures to the nonwoven material is used with the invention.
  • the carrier device can be a plate, for example a nickel plate.
  • the carrier device can be extended as a web or can form a drum.
  • the carrier device in accordance with the invention is regarded as being surface-shaped or two-dimensional in the sense that it does not have any projections or depressions. It has a plane and uniform surface.
  • a plate it consists of a sheet of plate with holes of different sizes.
  • the sheet of plate can be formed as a drum, although it does not possess any separate projections or depressions.
  • WO 03/083197 Described in WO 03/083197 , as previously mentioned, is a method for hydroentangling on a plastic gauze which contains holes. In conjunction with this, protuberances with the same height and size are produced in the nonwoven material.
  • protuberances are produced where second protuberances occupy an area of the base level at least 4 times larger than in the case of the first protuberances, where the protuberances have different heights.
  • Protuberances of this kind in a nonwoven material are not produced in WO 03/083197 .
  • pre-hydroentangling Before hydroentangling takes place, in which the surface structure is produced, pre-hydroentangling can be performed as described above. In conjunction with this, pre-hydroentangling is able to cause bonding together of the substrate web, which can take place on both sides of the substrate web.
  • the pressure exerted by the water jets is so high that the fibres are caused to be displaced on the carrier device, and they will penetrate down into the holes.
  • the ability to penetrate down into the holes depends in part on the physical size of the holes. A larger hole will permit the fibres to penetrate further down into the holes. This results in protuberances with different heights h 1 and h 2 on the nonwoven material.
  • Dewatering takes place in conjunction with the forming of the protuberances, and the water is drained away through the same holes in which the protuberances are formed. This results in the fibres moving easily on the carrier device and being displaced towards the holes and down into the holes.
  • the fibres on the carrier device that are present in association with the fibres that are drawn down into the holes will accompany them, and this will lead to the other side of the resulting nonwoven material exhibiting an essentially smooth surface.
  • the use of hydroentangling of the nonwoven material to impart surface structures produces a softer and more textile-like material with good strength characteristics.
  • the tangling together of the fibres in the hydroentangling process provides a good mechanical bond between the fibres, and good strength of the nonwoven material is achieved in this way.
  • the fibres are not damaged in conjunction with bonding together, as occurs in the case of thermal embossing, for example.
  • a soft and textile-like material is of great importance for absorbent wiping materials that will be used for wiping up.
  • the material will be soft and smooth, that is to say comfortable to hold during use.
  • a textile-like wiping material is also more attractive to look at, and a product which gives the impression of very high quality and strength is obtained.
  • At least two surface structures in the form of two protuberances 2, 3 are contained in nonwoven material, one background structure and one principal structure.
  • the protuberances in the structures exhibit different heights h 1 and h 2 .
  • the background structure has a lower height h 1 , since it is not the predominant surface structure.
  • the different heights of the surface structures mean that the base level of the nonwoven material will not always come into direct contact with the object to be wiped. This can be the skin of a user, the surface of a base to be wiped, etc. Particles of different sizes can be picked up by the absorbent wiping material. Slightly larger particles, which might otherwise have "slipped" away from a flat nonwoven material, will be capable of being picked up in a protuberance.
  • the fact that the protuberances have different heights means that particles of different sizes are picked up by protuberances of different heights. A better "carrying capacity" is achieved.
  • the protuberances will also make it easier to wipe places that are not readily accessible, such as corners or angles.
  • the protuberances are able to extend slightly further inwards than would otherwise have been possible with a flat nonwoven material. It is also easier to wipe uneven surfaces that are slightly rough, because the protuberances are able to reach down into the areas of roughness. Since the nonwoven material will have a number of different levels above the base level of the nonwoven material, the highest protuberances with a height h 2 will be able to reach further down into the areas of roughness in the ground, whereas the lower protuberances with a height h 1 will not reach as far down. Improved wiping up will be achieved as a result.
  • the quantity of fibres will vary between protuberances of different heights and extents and the material in the base level. This in turn leads to different pore sizes in different areas of the nonwoven material.
  • the pore volume distribution obtained on the side with a surface structure is thus broader than on a side without a surface structure and protuberances or with only a single surface structure. Larger pores have the ability, for example, to contribute to the better absorption of highly viscous substances and a better retaining ability in the material.
  • the second protuberances occupy an area of the surface of the base level of the nonwoven material at least 4 times greater than the first protuberances.
  • the protuberances with the height h 2 that is to say with the highest height, occupy the greatest area.
  • the fourfold difference in size accordingly gives rise to protuberances that are larger in terms of both their height and their extent.

  • the protuberances 25 can also been seen in Figure 2 .
  • a nonwoven material of this kind comprising additional protuberances with the height h 1 1 is produced in accordance with the method, in which the carrier device has additional holes that are smaller than the holes in the first patterns. Different sizes of the holes give different heights of the protuberances. The larger the hole, the higher the resulting protuberance.
  • Protuberances with heights between h 1 and h 2 can also occur, of course.
  • Additional surface structures can also be formed by protuberances with a different height and which occupy a different area of the surface of the base level than the protuberances with the heights h 1 and h 2 . More heights offer the opportunity to wipe up additional particle sizes when wiping up materials, and an even broader pore size distribution can be achieved, which is beneficial for the absorption capacity and the ability to retain highly viscous substances in the protuberances. More advanced surface structures can be created in addition. This also contributes additionally to imparting a more textile-like appearance, which is very positive in products of this type.
  • the carrier device 109 can also have additional holes which are smaller than the holes in the first patterns.
  • the nonwoven material obtained in this case comprises additional protuberances with a height h 1 1 that are lower than the protuberances with a height h 1 .

  • the polyolefins for example, are polyethylene or polypropylene.
  • An example of a polyester is polyactide.
  • the fibres can be produced from homopolymers or copolymers or mixtures thereof.
  • the material for the synthetic fibres can also be selected from amongst mono-, bi-, multi-components and mixtures thereof.
  • the fibres can also include regenerated fibres, which can be selected from amongst regenerated cellulose fibres such as rayon, viscous and lyocell.
  • the synthetic fibres are selected from amongst staple fibres, continuous filaments and mixtures thereof. Hydroentangling of fibres can be performed with both staple fibres and continuous filaments. An advantage associated with shorter fibres is that it is easier to create the desired surface structures. Continuous filaments require larger holes in the carrier device in order to be able to form protuberances.
  • meltblown or spunlaid fibres are preferably selected from amongst the continuous filaments, and the most preferred are spunlaid fibres. They should preferably possess a coarseness of 1-3 dtex.
  • the cross section of the fibres can be circular or trilobal, for example. Other cross sections are also conceivable.
  • the substrate web should preferably not be thermally bonded.
  • the filaments will then be capable of being displaced more readily on the carrier device and of being laid down and penetrating down into the holes in the carrier device in conjunction with the entangling process.
  • the method will still function if the filaments are thermally bonded.
  • Non-bonded filaments on the substrate web are achieved by cooling the fibres in conjunction with laying down to form a substrate web, so that they solidify before they come into contact with one another.
  • the staple fibres preferably have a length of at least 3 mm. Fibres with lengths of less than 3 mm are difficult to hydroentangle. They should preferably have a length not exceeding 60 mm, or not exceeding 50 mm. More preferable still, the staple fibres should have a length not exceeding 25 mm.
  • the staple fibres preferably possess a coarseness of 1-3 dtex. If thin fibres are used, the length of the fibres should be quite short. Otherwise, the risk is present that the fibres will become tangled together in clumps.
  • the cross section of the fibres may be circular, trilobal, star-shaped, hollow, etc.
  • the fibres can include micro fibres in the form of split fibres that are split at the hydroentangling stage, both continuous filaments and staple fibres, which possess a coarseness of less than 1 dtex. Such fine fibres give a smooth and soft product.
  • Nonwoven material in accordance with the invention can include natural fibres, which are selected from amongst cellulose fibres, pulp fibres, cotton fibres, ultimate flax fibres and mixtures thereof.
  • the nonwoven material contains pulp fibres.
  • the method in accordance with the invention preferably also includes pulp fibres in conjunction with hydroentangling. This is beneficial for the absorption capacity of the resulting nonwoven material, since pulp fibres possess a very good absorption capacity.
  • the pulp fibres will be present in a higher proportion in the protuberances than in the rest of the nonwoven material. This is because these fibres are more mobile and exhibit the ability to participate in the entangling when the fibres are sprayed with water jets.
  • Pulp fibres are irregular, flat, twisted and wavy, and they become pliable when wet. These characteristics mean that they can be easily mixed into and entangled with a web of continuous filaments and/or staple fibres.
  • Pulp fibres and regenerated fibres also possess a low wet module, with the result that they are easier to bend in the wet condition. This is of benefit for hydroentangling.
  • the resulting nonwoven material will thus contain a higher proportion of pulp fibres in the protuberances, with the highest proportion being present in the protuberances with the highest height and the largest area extent in the base level.
  • rapid absorption will occur when the protuberances first come into contact with a liquid that is to be wiped up.
  • pulp fibres are more opaque than synthetic fibres, for example, the proportionate increase in the protuberances will also result in the protuberances being much more clearly visible and in the production of a distinct image on the nonwoven material.
  • the proportionate increase in pulp fibres in the protuberances also leads to a rapid and increased absorption capacity in the protuberances.
  • the total density of the fibres may be lower in the protuberances. This is attributable to the fact that the hydroentangling process has not displaced sufficient fibres into the holes in the carrier device to compensate for the expansion that has taken place, with the result that the density is lower in the protuberances.
  • the expression "expansion” is used here to denote that the fibres have been able to expand into the holes in the plate and, in so doing, into the protuberance in the material.
  • Different fibres are displaced with different ease in conjunction with hydroentangling. Pulp fibres, for example, are displaced very easily, whereas longer fibres or continuous filaments may find it more difficult to be displaced into the holes.
  • the resulting nonwoven material will then have wider pores in the protuberances, which is advantageous for the absorption of highly viscous liquids.
  • Nonwoven material can also include other ingredients in the form of polymers, additives, etc.
  • Preferred weights per unit area for the nonwoven material in accordance with the invention are at least 30 g/cm 3 , or preferably 60 g/cm 3 .
  • the weight per unit area preferably does not exceed 120 g/cm 3 , or more preferable still 100 g/cm 3 .
  • a relatively high weight per unit area is required in order to be able to create a distinct surface structure.
  • the most preferable weight per unit area is ca. 80 g/cm 3 .
  • a preferred nonwoven material can contain 5-95% by weight of fluff pulp and 95-5% by weight of synthetic fibres.
  • the synthetic fibres are preferably selected from amongst polypropylene fibres, polyethylene fibres, polyamide fibres and polyester fibres, where the polyester fibres may be polyethylene terephthalate fibres.
  • the synthetic fibres can also be combined with 5-95% by weight of viscose fibres.
  • one embodiment can contain 20-80% by weight of fluff pulp or viscose fibres and 80-20% by weight of synthetic fibres.
  • the nonwoven material contains ca. 40% by weight of polyethylene terephthalate fibres having a coarseness of 1.5-2.3 dtex and a length of 15-20 mm, and ca. 60% by weight of fluff pulp.

  • the substrate web comprises several layers, or that several layers of substrate webs are transferred to the carrier device for hydroentangling.
  • the hydroentangling method that is used, with the drum as the base for producing the image or decoration, it is advantageous for the pulp fibres or regenerated fibres that they are hydroentangled down into the carrier material and, in so doing, form the desired three-dimensional surface structures.
